Hello MightyNate,
1.There was integration guide document under "integration_guide" folder as you have downloaded BSEC2.0.6.1 package. You could see sampling rate selection in document.
2, 3. In "BME AI-Studio document", it supported to export the algorithm as BSEC configuration file. Refer BME688 integration guide document for how to use it in your project.
